Hello,
I have a question re: calculations of efficiency and vrf in optseq2.
We are running two tasks. One is a reasoning tasks, with trial lengths of
12 seconds. The other is an embedded figures task with trial lengths of 10
seconds. For both tasks, we have set a minimum ISI of 4 seconds and a
maximum ISI of 10 seconds. In both tasks, we have two conditions we want to
compare and, thus, have devoted an amount of time equal to 50% of the time
devoted to tasks to total jitter time.
After running optseq2 for each task, we got the following statistics:
Task 1 (reasoning):
efficiency vrfavg0.04858156.44628
Task 2 (embedded figures):
efficiency vrfavg0.145069.22134
Is is a problem that the efficiency and average vrf are so much lower for
task 1 than task 2?
Thank you,
Dan
